Note: General Purpose Input/Output pins shown in Figure 1 are configurable to any specified input or output function in the SuperMux table detailed in Tab le 5 in the Module
Connections section.
Note: Connections shown in Figure 1 are maximum number of connections per function. The total number of GPIOs available on the CYBT-213043-02 is 22.

Module Description

The CYBT-213043-02 module is a complete module designed to be soldered to the applications main board.

Module Dimensions and Drawing

Cypress reserves the right to select components from various vendors to achieve the Bluetooth module functionality. Such selections will still guarantee that all mechanical specifications and module certifications are maintained. The CYBT-213043-02 will be held within the physical dimensions shown in the mechanical drawings in Figure 2 on page 5. All dimensions are in millimeters (mm).

To maximize RF performance, the host layout should follow these recommendations:
1. Antenna Area Keepout: The host board directly below the antenna area of the Cypress module (see Figure 2 on page 5) must contain no ground or signal traces. This keep out area requirement applies to all layers of the host board.
2. Module Placement: The ideal placement of the Cypress Bluetooth module is in a corner of the host board with the PCB antenna located at the far corner. This placement minimizes the additional recommended keep out area stated in item 3 below. Refer to
AN96841 for module placement best practices.
3. Optional Keepout: To maximize RF performance, the area immediately around the Cypress Bluetooth module PCB antenna may contain an additional keep out area, where there are no grounding or signal traces. The keep out area applies to all layers of the host board. The recommended dimensions of the host PCB keep out area are shown in Figure 4 (dimensions are in mm).

CYBT-213043-02

Connections and Optional External Components

Power Connections (VDD)

The CYBT-213043-02 contains one power supply connection, VDD. VDD accepts a supply input of 1.71 V to 3.63 V. Ta bl e 1 2 provides this specification. The maximum power supply ripple for this power connection is 100 mV, as shown in Tab l e 1 2 .

External Reset (XRES)

The CYBT-213043-02 has an integrated power-on reset circuit which completely resets all circuits to a known power-on state. This action can also be invoked by an external reset signal, forcing it into a power-on reset state. XRES is an active-low input signal on the CYBT-213043-02 module (solder pad 3). The CYBT-213043-02 does not require external pull-up resistors on the XRES input Refer to Figure 10 on page 17 for Power On and XRES operation and timing requirements during power on events.

HCI UART Connections

The recommendations in this section apply to the HCI UART (Solder Pads 28, 29, 30, and 31). For full UART functionality, all UART signals must be connected to the Host device. If full UART functionality is not being used, and only UART RXD and TXD are desired or capable, then the following connection considerations should be followed for UART RTS and CTS:
UART RTS: Can be left floating, pulled low, or pulled high. RTS is not critical for initial firmware uploading at power on.
UART CTS: Must be pulled low to bypass flow control and to ensure that continuous data transfers are made from the host to the
module.

External Component Recommendation

Power Supply Circuitry

It is not required to place any power supply decoupling or noise reduction circuitry on the host PCB. If desired, an external ferrite bead between the supply and the module connection can be included. The ferrite bead should be positioned as close as possible to the module pad connection.
If used, the recommended ferrite bead value is 330 , 100 MHz. (Murata BLM21PG331SN1D).

Bluetooth Baseband Core

The Bluetooth Baseband Core (BBC) implements all time-critical functions required for high-performance Bluetooth operation. The BBC manages the buffering, segmentation, and routing of data for all connections. It prioritizes and schedules all RX/TX activities including adv, paging, scanning, and servicing of connections. In addition to these functions, it independently handles the host controller interface (HCI) including all commands, events, and data flowing over HCI. The core also handles symbol timing, forward error correction (FEC), header error control (HEC), cyclic redundancy check (CRC), authentication, data encryption/decryption, and data whitening/dewhitening.

BQB and Regulatory Testing Support

The CYBT-213043-02 fully supports Bluetooth Test mode as described in Part I:1 of the Specification of the Bluetooth System Version
3.0. This includes the transmitter tests, normal and delayed loop back tests, and reduced hopping sequence. In addition to the standard Bluetooth Test Mode, the CYBT-213043-02 also supports enhanced testing features to simplify RF
debugging and qualification and type-approval testing. These features include:
Fixed frequency carrier wave (unmodulated) transmissionSimplifies some type-approval measurements (Japan)
Aids in transmitter performance analysis
Fixed frequency constant receiver modeReceiver output directed to I/O pinAllows for direct BER measurements using standard RF test equipment
Facilitates spurious emissions testing for receive mode
Fixed frequency constant transmission8-bit fixed pattern or PRBS-9
Enables modulated signal measurements with standard RF test equipment
